Skip grep, use awk

Here's the equivalent for Ruby:

    alias glorp='ruby -ane '

    $ [data is generated] | glorp ' ~ /Something/ and puts $F[2]'

Or:

    $ echo -e '{"hello":"world"}\n{"hello":"cat"}' | glorp 'puts JSON.load($_)["hello"] ' -rjson

(Of course Ruby got the -a autosplit-mode and the -n assumed 'while gets(); ... end' loop from Perl along with $_ and $F, so it's very intentional that they're similar)

Somewhat related nodejs self plug: Use nip https://github.com/kolodny/nip

    $  echo -e 'this\nis\na\nwhatever foo' | nip 'return /whatever/.test(line) && cols[1]' # foo

Awesome thanks for sharing this! I was too lazy to give a Ruby example alongside.

And Ruby regexes are amazing.

I thought that they were amazing because they were just like Perl's. Are there any differences?
